Formerly PTO

.

As we align our corporate identity with that of the international organization for PROFIBUS and PROFINET, PI (PROFIBUS and PROFINET International), we are now PI North America. Our new logo is in the upper left hand corner of the website. It uses the international logo and brings over the”North America” from our old logo. PI North America is one of 27 Regional PI Associations (RPAs) around the world. The other RPAs are slowly changing their identities as well. We now have PI Switzerland, PI Southeast Asia, PI Italia, and most recently PI North America.


We started out as PROFIBUS Trade Organization back in 1994 and shortened our name to PTO about five years ago. Now as PI North America we have the same office, same phone number, same URL, and the same people as when we were PTO. Call on us to help you get started with PROFIBUS and PROFINET.
